Be lznowntliat Ldviiiiitaiir CBUMP- TON, acit zen. of the United States, residing at Evanstori, in

qystenis,- (Case 16,) of which the following is aflfullpclear, concise, and enact descriphad'to the accompany ing drawings, forming afpartlof this specificatmmv. W

My invention relates to electricallycom governed 'ac-I counting systems, is particiii'larly appli-' and "cost-accounting, where the entries'made are lle i and a t it l tielly" cableto systems of time, wage-' ,"job-' geiicially but not necessarily functions of time.

The system whiclil have herein set forth as illustrat ng onetmbodiment of my in vention, comprises "individual as well. as-

totalizing registers -'grouped"'and arranged to form substat ons.

These" substations are connected in multiple with'a source of electric impulses and include ditt'erential'mo-i I tiTr' mechanisms for discharging theentries at the same time; that they accumulate, into a generic receiving station. simplicity I havef-sh'own the substations as discharging'into fla' central station where all, It is, obvious,- 7 may be interposed betweenthe substations and the final receiving station". 7

i The registers are actuated by means of a three-phase motor "associated with each register.

the registers in either direction according to the order in which the electrical impulses are impressed upon the' different phases of the motor. I do not herein lay claim broadly to such a three-phase motor, since that is a feature claimed in my'co-pei'id'ing application Serial No. 498,547, filed May 26, 1.909.

The differential motor mechanism herein shown (which I prefer tocall a substation ei t vt" owl; n State of Illinois, have invented certain newand' useful 1 Improvements in Accounting For the sake "of of impulses. These motors are energized'from a. source of three-phase current impulses. The

rate of actuation of rates may be. produced; Thus,

uni'tyi' o constructed that the cycles in PYQSSBd'HPOIl it may cause a resultant inot'ion of the arn'iature:equaltozer'o. There are various ways in which this uiay-beca'rried. out,

I In the partieularfform "herein illustrated, a substation unit is 'provided with .two'sets of three-phase windings, one

set being connected in circuitwith the indi vidual wage registers to actuate the armature in one dirfctiong while the other set is I connected with thevf registersht' the central station and is adaped'to actuate the armature the reversetdirection; Because of th s characteristic hii'od'e "-of' operation of these" substation un i'ts, "I have i come to desigiiate (and aptly," I' think) the substations as'ballistic substations. Specifiodetailsregarding the precise operation and function due course; I might hereinention'that one of the great features of these substation units is their remarkablesiniplicityfthere being atotal absenceof su'ch mechanical encumbrances as diflerential gears.

the system disclosed n my eo-pendin'g appl cation above referred to, the rate controlling-mechanism must be partially duplieatedfor' eachsubstation, if it is des'iredt'to have the rates prevailing in the yarious substations entirely independent of'ea'ch other.

Now, in the present system, this freedom or T independence of rates between substations is secured by a single rate controlling mecha- "nism for the ent re systenntlie substations being connectediIi-m'ultiple with the source provided with a rate connecting-board for involving each workmans register with a particular rate. I By varying the number of times that a wage register is connected during a predetermined period, different a register Whose circuit isclose H vice as often as that of another registertluiing the same period,

will operate 'at twice the rate of that other uniform rate, irrespectiveof the rate of actuation of the connected wage-registers, I

. have made provision whereby the time-regis ters will become locked after the proper number of impulses has been sent through of these. ballistic substations will -folloiv' in 9'0. Each substation is, of course,

them in a given period, without in any way interfering with the further actuation of the wage-registers during that period. By means of a selector mechanism serially included in the connections between the source of impulses and the substations, the work- 'mens registers in any substation are successively selected for actuation, while the corresponding registers of all of the substations are selected for simultaneous actuation. I have already mentioned that the substa tion units receive impulses through the individual wage-registers tending to actuate the armatures in a certain direction. These impulses are what might properly be termed accumulating impulses. The impulses, which these substation units receive through their connections with the totalizing registers at the central station, I designate as transfer impulses, since they tend to cause rotation of the armatures in the reverse direction. If these opposing impulses occur simultaneously in a substation unit, there will be. no motlon of the armature, and for every accumulating impulse passing through .the workmens wage-registers, there will be a transfer impulse passing through the corresponding totalizing reglsters at the central station. The accumulating circuit connections are such that, as already mentioned, the

corresponding wage-registers of the various substations will be actuated simultaneously. Thi means, of course, that the corresponding. substation units will be simultaneously subjected to accumulating impulses. 'The transfer circuit connections, however, are

- central such that the substations-are connected successively with the grand totaLregist'ers at the central station. This means that the corresponding units of the different substations are subjected one after the other to transfer impulses. The result of this arrangement is that a, substation unit will, at

one time, be subjected to accumulating impulses and transfer impulses concurrently and at another time receive the opposing im pulses inter-currently. As already explained, when the opposing impulses take place con currently, there will 'be no motion of the armatu-reat least the tesultant motion will be equal to zero. However, when the oppos ing impulses take place in'tercurrently, the armature will be actuated in a certain direc tion under theinfluence of the accumulating impulses. After a predetermined amount of such rotation of the armature, the circuit is automatically closed through the transfer windings and the armature is rotated in the reverse direction an equal amount, whereby the same number of impulses that passed through the accumulating windings will be sent through the totalizing register at the through the transfer windings is automatically opened and the accumulating windings reference characters, Figure 1 is a diagramstation. Thereupon the circuit may again produce rotation. These substation units really takethe place of individual job-registers and might, in fact, be considered as such, except that they'are not provided with any numeral wheels. They" are not intended to give any indications, but merel serve as channels for receiving and trans errin'g individual wage-accumulations into the corresponding totalizing registers. Many other characteristic features of my invention will present themselves as the specification proceeds;

Referring to the drawings Where the corresponding parts are indicated by the same matic illustration of my invention showing the circuits and thevarious controlling devices for effecting the accumulation of the registers, Fig. 2 is a diagrammatic representation of t e transfer circuits and controlling devices, Figs. 3, 4 and 5 are more or less diagrammatic indications of the differential motor mechanism, the armature being shown in the various positions it will assume under the successive energization Ofl the windings, Fig. 6 is a view partly. broken away of a register detail showing how the .circuit through the register actuating device is automatically interrupted as the register passes through zero, Fig. 7 is a sec tional side view taken on the line 77 of Fig. 6, and Fig. 8 is 'asideview of a substation unit showing the arrangement whereby the circuit through the transferwindings is automatically opened and closed after a certain amount of rotation of the armature in either direction. Fig. 9 is a top View of the parts shown in Fig. 8. I.

I think that an understanding of'the op eration of my system will begreatly facilitated, if I first explain the construction and I worklng of the diflerential motor mechanism as shown in Figs. 3', 4, 5 and 8. Calling attention to Fig. 3, the magnets 1, 2 and 3 and the armature A are so'arranged that if winding Aa is energized, the armature will be rotated counterclockwise into the position shown in Fig. 4. If next the winding Ab is energized, the armature will be rotated one step mto the position in, which it is shown in Fig. 5. If now the winding Ac be energized the armature will receive another rotation in the same direction until it assumes a position identical with that shown in Fig. 3 so far as the angular disposition 'of'the armature blades is concerned,that is to say, after actuation of the armature by the winding Ac, it will be again in'a position to be acted upon by the winding Aa to commence a new cycle of rotations. It will be seen, therefore, that by sending successive electrical impulses through the windings Aa,

Ab and Ac, actuation of the armature is produced in a certain direction, indicated'in the drawing-as counterclockwise. A set of three impulses may thus. be considered a cycle. Considering now the' outer, set of --w1nd1ngs shown in these figures,- it will be.

apparent that if winding Ta beenergized while the armatureis in the-position shown .inF-ig. 3, the armature will be rotated clock wiseyas indicated by the outer pair of ar *rows, into theposition shown. in Fig. 5.

. Then if :the winding T?) be subjected to a 10' current impulse, the armature will begin another movement clockwise into the positionin which it is shown in Fig.;-;t. ,If the cycle of impulses be completed by the energization of designated Ta, Tb and transfer windings.

Returning now to Figs. 3, 4 and'5,it will be apparent that withthe; armature inthe position indicatedin; Fig. 3, the simultaneous energization of the windings Am and Ta, in no, rotation-of the armature,- for the reason that the effects of the windings upon the armature are equal and op- -Similarly, if windings Ab and Tb are simultaneously energized, there will be no rotation of the armature, and the same is true if there is a simultaneous energization of the windings A0 and To. It will thus be seen that the windings of this motor mechanism may be energized in pairs a way to cause no rotation of the armature, at least, in a way such that the resultant rotation of the armature is zero for every cycle of impulses. It may happen that in the actual ht be armature in occupying a position sponding to that shown in Fig. 3, mig

than to that of another. The unbalancing might be sufiiclent to cause rotation of the armature even under the influenceof opposing windings.

For instance, referring to Fig. 3, we mightsiippose that the armature was in. greater proximity to the core of winding Aa than to the core o'fwinding Ta. Simultaneous' energizing of "these 'wi'ndings would'cause the armature to be actuated by winding Aa, substantially into the position in which it is shown in F ige.

The next pair, of windings to be'energized I The armature being" in thel'position shown in 4, would'suffer no movement for the reason that one of the arms of the armature .is directly opposite the core of the winding Tb. The cycle would be completed by thev simultaneous energization of windings Ac and To, which woul gcause'movement of the armature clockwise J cm the position shown in Fig. 4 to thepo sition shown in Fig. 3,

which was the position of the armature at the beginning of the cycle.

r In any event, therefore,the eifectl' of cyclicallyenergizing the windings in pairs, as above described,

will cause theresultant rotation of the armatureftobe equal to zero. Considering the I motor as a-,unitary structure independent of its specific use-in connection withthej sys tern, it will be evident to art that there, are other ways for producing the ballisticefi'ect uponv the armature." For instance,.instead of setting up fiirXes which act uponfthe ar nature-opposingly, each pair of opposing windings might be arranged upon the same core a'nd'so connected .1n circuit that the fiuxes produced by the energization of these windings would be equal and one winding might be made to neutralize opposing sources of elec This would prevent current from flowing'through the windingand wouldbeno flux to act upon theft-FY1121- Although I have illustrated only the first way of producing the desired efiect upon the armature, I will have it understood thatI do not, by anymeans, intend to limit myself to such a construction, as indicated in certain of the appended claims.

From the above 'description of my threephasemotor-mechanism, it will be clear that as longas the impulses are cyclically sent through the windings Aa, Ab and A0, the armaturewill be rotated counterclockwise. Inasmuch, however, as these motor-mechanisms are not intended to give any indicaconnections to two tions of the entries accumulating therein vent extensive actuation of the armature unthose skilled in the Inother words, the flux due to' One convenient way of'carrying this out is shown in Fig. 8, where the two contacts 4 and 5 control the circuit through the transfer windings, as diagrammatically indicated in Fig. 2. The contact 5 is connected with the spring-arm 6 which engages the peripheries of the disks 7 and 8 and normally tends to separate the two contacts. The disk 7 is fixed upon the shaft 9 and is provided with the stud J0 as well as with a cam surface 11,

the latter bcingindicated in dotted lines in- F 8. The disk 8 is rotatably mounted upon the shaft 9 and has a slot 12 to accommodate the stud 10. On the shaft 9 is also mounted the gear 13 which meshes with a smaller gear 14 carried by the armature shaft 15. With the parts in theposition shown in Fig. 8, the circuit through the transfer windings is closed by the contacts {l and 5 and the winding next to be energized will be the winding Tu whichwill move the armature one step in a clockwise direction, causing the gear 13 and fixed disk 7 to move counterclockwise. By virtue of the pin and slotengagement between the fixed disk 7s and the loose disk 8, the latter will be dragged along by the disk 7 in' a counterclockwise direction, as can be clearly gathered from Fig. 8. This clockwise rotation of the armature underthe influence of the transfer windings will continue until the slot 16 in tile loose disk 8 comes directly under the pro ection of the spring arm (iwhereupon the latter will drop into said slot and cause separation of the contacts 4 and 5. This,-of course, throws the transfer windings temporarily out of commission and gives the accumulating windings a chance to pre-' dominate. The rotation of the armature by the accumulating windings will be counter clockwise, as already explained. During this actuation of the armature the disk 7 will be rotated clockwise While the disk 8 will remain stationary. This is due to the fact that the Stud 10 on the disk 7 will travel in the slot 12 of-the disk 8. During this clockwise rotation of the disk 7, the projection on the arm 6 will ride up the cam surface 11 until the disk is in the position in which it is shown in Fig. 8, where the arm 6 is shown as raised on the highest portion of the cam surface. The contacts 4 and 5 will therefore be again closed." This will cause the transfer windings to be again energized and the disks 7 and 8 will be rotated counterclockwise as above described to separate the contacts. This cycle of operation Will be repeated as long as the two sets of windings -are not energized concurrently. For the sake of convenience and simplicity the two sets of windings have, in Fig. 8, been shown as superposed. With this description of the operation of the substation unit, we are now in a position to turn our attention tothe system as it is diagrammatically indicated in Fig. 1. Upon the time-controlled impulse-shaft IS'is fixed the disk D provided with the single tooth 17 which is adapted to engage the Geneva wheel G. i It will be seen that for every revolution of the disk D, the Geneva wheel is rotated one quarter of a revolution. The shaft IS is shown as consisting of two insulated portions, one of which carries the impulse-disks (la, (lb and do, while the other portion supports a set of similar disks cla, (Zb and clc. The selector-shaft SS, upon which the Geneva wheel is mounted, is shown as divided into a plurality of insulated sections upon which are mounted the selector-brushes Associated with three of'thc selector brushes are the three phase motor selecting disks or commutatols SDa, SIM and SDc. The fourth selector-brush has associated therewith the time-selector commutator T S which is similar to the other commutators, Upon the insulated end 18 of the selectorshaft is secured the cam 19 for periodically actuating the rate-controlled mechanism, as will be hereinafter explained. Of course, it

is obvious that the necessary insulation of the. parts may be accomplished in ways other than that shown. For the sake of simplicity of illustration the shafts IS and 58V are shown in sections insulated from each other. Cooperating with each-of the commutators is a'brushQO. A conductor 21a connects the brush of the disk do with the brush of the phase-selecting commutator SDa. The brush of disk db and the brush of the phase-selecting commutator Sdb are electrically c011- nectedby the conductor 21?), while the 0011- ductor 210 connects the brush of disk (la and the brush. of the phase-selecting commritatorSDc.

With regard to the reference characters used to designate the various impulse-disks and phase-selecting commutators, I will explain that I have added sufli-xes a, b and c to designate the different phases of eachcycle of impulses, Thus, for instance, .theim'pulse-disk do. is the disk which ,connects the battery in circuit for the aphase impulse of each cycle, while the phaseselectingcommutator SD11 connects the a.- phase impulses to be sent through the register circuits. In this way, by paying attention to the sufiiXes used in certainof the reference characters, the different phases of the cycles of impulses may be traced in the various circuit connections.

Each of the phase-selecting commutators consists of a plurality of insulated segments. For the sake of illustration the number of segments shown is four for each commutator. This is because," in the particular dis;

A set of three bus-Wires Bla, B11) and 1310 is connected with the segments. N01- 1 of the phase-selecting commutators SDa SD?) and SD respectively. To: this set of bus-wires is connected the workmansindr' vidual,wage-register} 101w and the worknians time-register 10115, which registers, it will be observed, are serially connected. It may be supposed that these registers are as-f signed to workman No. 101 of substation S1. A similar set of bus-wires B211, B212 and B20 is connected with Segment-s'NOQ 2 of the phase-selecting commutators SDa, SDb and SDc, respectively, To this st of bus-wires are connected the wage-register 102w and the time register 1022i, which mayv be supposed to be assigned to workman No. 102- of the same substation In. a similar manner the remainingsets of bus wires are. connected to the rema ning segments of the. other phase-selecting. commutators. In words, av set of bus-wlres leads from every workmans wage and -time-reglster ma sub "station to the phase-selecting commutat ors. I

Associated with the selecting commutator WD is the brush SB fixed upon the s'ubsta-j tion selector shaft; SSS which receives mo tion from the selector shaft SS through the medium of gears 22. Besides thecomtnuta tor WD for selecting the individual time-If and wage-registers for connection, the substation selector mechanism comprises also the commutator JD for selecting'the station units and the commutator RD 7 for successively selecting the rates. A brusharm is associated with each; of those" pommutators. It will be observed tliat the coni. mutators of the substation selector mecha nism are similar to the phase-selecting corn mutators and that the'. brushes of theftwo sets of comlnutators areso disposed on their respective shafts that corresponding s gments are engaged at the' same time. Y Gonsidering the. parts, as' shown in Fig.1, it

willlbe seen that the brushes of the'pha'se;

selecting commutators and a the disks of the substation: selector mecha nism are all jengagementgwith segments No. v1 of the r;

associated commut'ators. When the selector shaft; SS is' actuated to move the brushes carried thereby from segments j No. {1 "to segments No. 2, the substation selector shaft SSSY will be; rotated to c'arrythe brushes thereon from segments cNo. Ito-segments N 0; 2 of the associated commutators RD and l he bru'she's on the shaft SSS are shown insulated tra each other byv beingimounted upon'insulated sections of theshaft, similar to themounting offthe brushes onl theselectdr om the .g

to 34 and the common conductor 35 which leads to the accumulating windings of the substation unit VVV. Each strip of jacks in the switchboard J S is representative of a job. Thus, a plug inserted in jack strip jsl would connect a workman with job No. 1; a plug inserted in jack-strip 3193 would connect a workman with jobNo. 3; and so on. The number of jacks in any one strip may, of course, be sufiicient to accommodate all of the workmen in that department of which the substation is representative; so that all of the workmen in that department may be assigned to one and the same job.

From the jack-strips of the job-switchboard J S lead conductors 41, 42, 43 and 44 to the accumulating windings of substation units SUI, SUQ, SU3 and SU4, respectively. At their other ends,'these windings of the substation units ww and SUl to SU4 are connected to the three conductors 36a, 36b and 360. The accumulating windings of the substation unit TVV are included in the connections between the conductors 36a,-

36b and 860 and the set of bus-wires Ba, B?)

and B0, so that the accumulating impulses passing through any one of the substation units WW and SUI t'o SU4 will also be impressed upon the accumulating windings of the substation unit TVV. The latter, therefore, serves as a totalizing unit for the other units of the substation; or it might, perhaps, be better to state that the unit TVV' receives impulses at a rate corresponding to the sum of the rates at which the impulses pass through the workmens individual wageregisters 101w, 102w, etc. As the substation units in this system are nothing more than electric motors, the total wages earned will not be indicated by TW but will be transferred, as will appear later, into a grand total register at the central or final station. 'The substation unit WW is also a totalizing unit in that it receives impulses that pass through the wage-register of the workman whose switchhas been thrown to the in position but who has not been assigned to any particular job. It is, of

course, obvious that when a workman arrives in the morning andthrows in his switchhe should not be deprived of his wages during the time in which he has not been assigned by the foreman to some job. The substation unit WW has therefore been provided to receive the impulses that pass through a workmans register when he is not connected with any particular job. In such a case a workmans job-plug will be out of position on the switchboard J S and the spring contacts of the plug jpl will be closed as is the case with the plugs jpQ, 7'7)? and jp4'in Fig. 1. When a plug is in the out position the impulses passing through the connected wire 31, 32, 33 or 34 from. the connected wage -register will pass through the job-plug into the accumulating windings of the unit \VVV by way of the common wire 35. When, however, a plug is inserted in the job-switchboard, the impulses passing through the connected wire will not enter the unit but will pass into the proper substation unit SU1 to SU4. The unit TVV receives the impulses that pass not only through the job-units SUl to SU4 (as they may be termed) but also those passing through the waste wage unit WW.

The bus-wires Ba, 13?; and B0 act as common conductors for the various substations which are connected. in multiple thereto. Thus, in Fig. 1, the substation unit TW' is connected to the bus-wires in parallel with the corresponding unit TVV of the substation S1. The substation unit TVV is so connected with the other units of that substation as to P8061178 all of the impulses passing therethrough. In this way the units TVV, TlV, etc., act as totalizers of the numberof impulses passing through the other substation units. The brushes 20 of the impulse disks (Za, (Zb and (Zo are connected with the bus-wires Ba, Bl) and B0, respectively. It will be observed that the segments of the disks da, (ZZg and (Z'c bear the same angular relation toward their associated brushes as the segments of the disks da, (lb and do bear toward their brushes. That is to say, when a segment of disk da is in engagement with ,its brush, a corresponding segment of the disk do will make contact with its associated brush. The only reason why the segments.of corresponding disks are shown displaced by an angle of 180 degrees is because, for the convenience of illustration, one set of brushes is shown displaced 180 degrees with respect to the other set of brushes. The s ments of the disks da, 03'?) and dc are connected with one side of the battery through the conductor 37 while the segments of the disks da, db and do are connected to the opposite side of the battery B through the conductor 38. This brings us to the rate-controlling mechanism and the circuit connections therefor. From the common conductor 39, which is connected with one side of the battery B, leads the wire 40 which terminates in the common bus-wire To this wire 50 is connected at each substation one side of the winding 51 of a solenoid switch having a movable core 52. The other side of the winding is connected through conductor 53 With the brush of the rate-selecting commutator RD. When the winding is energized the iron core is actuated to close the contacts 54 and 55, thereby electrically connecting the brush of selector commutator WD with the brush of selector commutator JD through the conductor 56 and the switch S. To the segments of the rate selecting commutator RD are connected conductors 61, 62, 63 and 64 which terminate gage their respective brushes in order to closethe circuit for the brimpulse of the cycle through the same registers and substation units. Then when the segments of .the disks do andrlc come into engagement with their respective brushes,,the circuit connections will beclosed for the c-impulse of the cycle. The circuits for the b pha'se and c-phase impulses are so analogous to the circuit which has been traced in detail for the first impulse of the'cycle that it is not believed necessary to trace the circuits in detail for. the other phases of the cycle.

' Those circuits will be readily understood from the circuit of the first impulse of the cycle. It will, of course, be realized that as the impulse shaft rotates to bring the seg ments of the various impulse disks successively into engagement with their brushes, the selector shaft SS, the substation selector shaft SSS, as well as the rate shaft RS re upon the particular jack-strip in the switch boards J S with which the jack-plug i772 (which is assigned to workman No. 102) has been associated. Otherwise, the circuits through the registers belonging to workman No; 102 will be the same as the. circuits which have been traced in connection with the registers of workmanNo. 101.

For the sake of having a clear understanding of the mode of operation of the rate-cons trolling nechanism, itv has been assumed that the workman receives one cent in wages for every cycle of impulses sent through his register and that a register is selected for-connection once every two minutes, or, as it. is commonly put, a workman is picked up once in every two minutes. The impulse shaft TS wilL'therefore, make two revolutions per minute, which will cause the selector shafts SS and SSS to make one revolution every two minutes. The ratchet wheel 65 is provided with thirty teeth. Once in every revolution of the shaft SS, the ratchet wheel, as already explained. will be moved the distance of one toothwhich is one-thirtieth of a revolution. From this it follows that the rate-shaft will make one revolution per hour. The rate-disk R1 has been designed to represent a rate of ten cents per hour. It will be remembered that the workman is selected for connection once during every revolution of the shaft SS. Now, inasmuch as this shaft makesthirty revolutions per hour to send thirty cycles through the circuits of the system it follows that if-a rate-disk were in of those thirty revolutions of'the shaft SS, such a disk would represent a rate ofthirty cents per hour. However, by so constructing the disk that during certain revolutions of the selector shaft it remains in an open position, any desired rate may be secured. Thus a disk to represent-ten cents per hour would occupy a closed position only during ten revolutions of the shaft SS every hour. Such a disk is the rate disk R1. It will be observed that this disk is provided with ten segments equally distributed around the pe-, riphery of thedisk. This means that the disk will be in a circuit closing position during every third revolution of the selector shaft. Considering that the disk will close the circuit during the first revolution in every hour ofthe shaft SS,-the ten revolutions during which the disk would cause the circuit of the connected register to be closed, would be the following: 1st, 4th, 7th, 10th, 13th, 16th, 19th, 22nd, 25th and 28th. During the intervening, revolutions, the brush of the disk R1 would engage the insulation between the segments. The rate disk R2 represents, a rate of fifteen cents per hour. This is obtained by so constructing the disk that 15 of the 80 revolutions per hour of the select-orshaft SS are lost, as it were. --.That is to say, during those 15 revolutions, the brush of the disk will engage the insulation between the segments. It will be observed five in number, which are narrower than the five interposed segments. The object ofthis arrangement is to have each of the five nar-' row segments close the circuit during one revolution of the impulse shaft, while the wide segments close thecir'cuit during two consecutive revolutions of the impulse shaft. Accordingly, there will be fifteen revolutions during which the rate-disk R2 will occupy a circuit-closing position, those revolutions being the following: 1st, 4th, 5th, 7th, 10th, 11th, 13th, 16th, 17th, 19th, 22nd, 23rd, 25th, 28th and 29th. The rate disk R3 has been designed to represent a rate of 20 cents per hour. This isobtained by causing the disk to be in open-circuit position during 10 out of the 30 revolutions per hour of the selector shaft SS. -Each of the ten segmentswit h which the disk is provided allows the circuit to remain closed for two consecutive revolutions of the selector-shaft, thus closing the circuit for twenty cycles. This disk assumes an open-circuit position every third revolution of the impulse shaft, these revolutions being the following: 3rd, 6th, 9th, 12th, 15th, 18th, 21st, 24th, 27th, 30th. This, of course, is on the assumption that during the first two revolutions the brush is in contact with one of the segments.

a circuit closing position during every one that there are certain alternate segments, I

If, at the beginning of the hour, the brush engages an insulated portion of the disk, the ten lost revolutions would be distributed accordingly. In any casethe re sult is precisely the same. Concerning the highest rate-disk R4, which represents a rate of twenty-five cents per hour, it will be observed that it is provided with five wide segments separated by relatively narrow pieces of insulation. This disk assumes a circuitopening position during five of the thirty revolutions of the selector-shaft SS. If we consider that 'at the beginning of the cycle of revolutions the,brush of this disk is at the commencement of a segment then the five revolutions which are omitted by the'disk are the following: 6th, 12th. 18th, 24th and 30th.

I- have gone into the above detailed explanation of how the rate-mechanism shown in the drawings has been designed to represent certain rates, in order to make clear the theory. of operation of the rate-mechanism. It will now be understood that, given a certain period, say one hour. the rate at which a register will be actuated depends upon the number of times during which the circuit of that register has been closed during every hour. The rate-disks'control the register circuits through the instrumentality of the solenoid switch which controls the contacts 54 and 55 included in a common conductor of the register circuits of each substation. As may be seen from Fig. 1, the circuit of any one wage-register can be completed only through the conductor 56. Unless the winding 51 of the solenoid switch is energized by one of the rate-disks, the register circuit will remain open. There is a rate plug for every workman, and the workmans rate-disk is selected simultane ously with the selection of his individual wageand time-registers. Thus, in Fig. 1, the registers assigned to workman .No. 101 are selected by the brushes of the commutators WD and .JD engaging the associated segments No. 1. At the same time the brush of the selecting commutator RD is in engagement with segment No. 1 with which the workmans plug is connected. If, while the workman is thus selected for connection with the rate mechanism, his particularratedisk is in circuit closing position, the contacts 54 and 55 will be'closed and an impulse will be sent through his registers. On the other hand, if the rate-disk is in a position in which the associated brush engages the insulation, the circuit through the workmans register will remain open.

Inasmuch as the workman s individual Wage-register and time-register are connected in series, it stands to reason that some provision must be made for securing a uniformity of rate of,actuation of the time register, irrespective of the rate at which the associated wage-register may be actuated. For, the function of the time-register is to indicate lapsations of time and should not be influenced by the rate of actuation of the connected wagercgister, since that'rate is arbitrarily determined and may be varied whenever desired. To render the rate of actuation of the time registers proportional to the lapsed time, no matter what the rates of actuation of the connected wage-registers may be, I provide the actuating device of each time-register with a locking winding, the object of which is to lock the register against actuation beyond a certain amount during every hour.-

In Fig. 1 it will be observed that the timeregisters are diagrammatically shown as being provided with three windings connected at one end to the bus-wires Bla, Blb, B10,

and BZa, B21), B20, etc. On one of the cores of the three-phase motor which actuates the time-register, there is an additional winding. This winding, in Fig. 1, is indicatedas being carried on the same iron core as the c-phase winding. I'might perhaps be better able to explain the locking function of this winding if I again direct attention to the diagrammatic illustrations in Figs. 3, 4 and 5'. If in these. figures we imagine the windings-Ta and Tb removed, we get the precise mechanism for actuating the timeregisters. It has already been described how rotation of the armature is produced by sending a cycle of impulses successively through the windings Aa, Ab and A0. Now, if after the momentary energization of the c-phase winding Ac,the additional winding Tc should be'energized, the armature would remain in the position in which it is shown in Fig. 1 so long as that winding remains energized. The energization of either the winding Aa, A5 or A0 would not afiect the position of the armature. In other words, so long as the extra winding Tc remains energized, the armature is locked against movement. In Fig. 1 the locking windings of the time-registers 101T, 102T,

etc, are included in the connections L1, L2, L3 and L4 respectively. The locking windings of corresponding time-registers in the various substationsare included in series in the same connections. For instance, the locking windings of the time-registers 10125 and 2012? are serially connected with the conductor L1. The locking windings of the time registers 1022i and 202t are serially connected with the conductor L2, and so on. One end of the conductors L1, L2, L3 and L4 is connected with segments Nos. 1, 2, 3 and 4, respectivelyflof the selector commutator TS. At their :other end these conductors are joined to the common conductor 39. The circuits of the locking windings of the different-time registers are controlled by the time-locking disk TL fiXed upon the rate-shafttRS. In the particular example illustrated, it has been assumed that ber of cycles depending upon the rates involved. It is the function of the time-locking disk TL to so control the circuit of the locking winding of a connected time-register, so that the same will receive only ten effective cycles-of impulses every hour. Inasmuch as the rate-disk R1 permits only ten cycles per hour to pass through the register operating at a ten cent rate, the locking circuit of such a register will not'come into play. Consequently, whenever a segment of the disk R1 engages with the associated brush, the brush of the time-lockin disk will engage an insulated section. et us suppose that a register is operating at the rate of fifteen cents per hour, and is, therefore, connected with the-rate disk B2. In that case, whenever the brush of rate-disk R2 engages one of the five narrow segments, the brush of the time-locking disk TL will engage an insulated section. The relative angular disposition of the wide segments on thejrate-disk R2 and the segments of the disk TL is such that for one of the two consecutive revolutions during which the brush of the rate disk remains in engagement with each one of the wide segments, the brush of the time-locking disk will be in engagement with a segment, but will engage an insulated portion of the disk for the other revolution. In consequence, the circuit through the locking winding of a time-register whose associated wageregister operates at a fifteen cent rate will be closed and the register locked against the influence of five of the fifteen cycl'esswhich pass through the wage-register every hour. In a similar manner doesthe disk TL operate to close the circuit of the locking disk for ten of the twenty cycles which the rate-disk R3 allows to pass through the connected register. When a register operates at a twenty-five cent rate, the time-locking diskcloses the circuit for fifteen cycles every .hour. We can readily trace one of the locking circuits by supposing that the brush of the time-locking disk is in engagement with one of the segments. The selector-brushes being in engagement with segments No. l of the various selector commutators, the locking circuit will be completed through the corresponding time-regis ters 101$, 2012?, etc., as follows: from one side of the battery to conductor 39, thence to the conductor L1, then serially through the lockin windings of the registers 2011. and

10lt, rom there to segment No. 1 'of the time-selector commutator TS, then through the associated brush toconductor 86, from there to the disk TL, shaft RS, conductor 72, conductor 73 and back to the other side of the battery B. As the selector shaft SS is rotated, the brush of the selector-commutator TS will engage the 7 other segments successively, thereby successively connecting the other time-registers of each substation with the time-lockingdisk.

y In explaining the mode of operation of my system as shown in Fig. 1, and tracing the various-circuit connections, I have made specificre'ference to substation S1 only. I do not deem it necessary to repeat the above description withreference to the second sub- .station S2, or any other substations, for the reason that the circuit connections are merely duplicated for the various substati'ons. Therefore, a detailed-description with reference to any one substation is sufiicient for a complete understanding of my invention. The only thing that remains to be said in connection with Fig. 1, is about the clearing circuit of the Wageandtime-registers. It may sometimes be desired to set these registers to zero. This is accomplished by reversing the direction of rotation of the shaft IS and throwing the switches S" into engagement with the contacts 76. By reversing the direction of rotation of impulse shaft IS, there is a reversal of the order in which the impulses are impressed upon the windings of the three-phase motors that actuatethe wage and tlme-registers. This will cause the armatures of the registers to rotate in a decumulating direction to bring the-numeral wheels back to their zero position. It is obvious, however, that the registers might be set to zero by forward actuation. The clearing circuit for one of the impulses may be traced through the registers 101i and 101w as follows from one side of the battery B, to conductor 38, to disk do, conductor 21a, segment 1 of selecting commutator SDa, registers 1011*. and 10120, contaots'7 5 and 74:, conductor (11, switch S, segment 1 of selector commutator WD, conductor 56, across the contacts Y54; and '55, switch S1, contact 76, conductor 77, conductor 78, conductor 73 to the, other side of the battery. The clearing circuitsfor the other phases of'the: impulse cycle and the other registers may be traced similarly. As a register is brought back to zero, the contacts 74 and 75 are automatically opened to break the circuit through the register and thereby revent the same from going beyond zero. T ere are many ways in which this may be accomplished, one simple way being shown in Figs. 6 and 7. The hi hest order wheel hasconnected therewith a s1: 79 provided with a cam portion 80. With the disk Y 79 cooperates an arm 81 having slotted engagement with the shaft 82 and being provided with a pin or stud 83. This arm ,abuts at its' upper end against the contact 74; The

- tion of the register beyond zero, or rather,

to speak more accurately, beyond the nines position. In order to place the reg.- 1sters in condition for normal operation after being actuated reversely to the nines position it is necessary to give the registers a forward actuation suflicientto bring them from the nines to the-zero position. There are several ways in which this might be done, but one ofthe simplest is to cause a 'cycle of impulses to be sent through the cleared registers. To accomplish this, the workmens wage and central station registers are provided with an additional contact 125 adapted to cooperate with the contact 7a tov close the circuit when the contact 7 4 is thrown out of engagement with the contact 75 asthe register wheels pass to the nines position. The additional contacts 125 are connected with a common conductor 126' which leads to the f battery through a suitable switch 127. Upon properl manipulating this switch in connection wit the forward runof the gear controlling contact mechanisms, an electrical cycle may be sent through the proper registers, thus causing them all toindicate Zero and atthe same time close their normal forward running contacts. This placesv the registers in condition for receiving the register routine entries.

We will now direct our attentionto the transfer operations of my system. T have stated in the fore part'of this specification that the substationunits are simply motors with no registers andno'diiferential gears, serving merely as a medium for causing actuations equivalent to those of the .connected wage-registers to be transferred into the total registers at the central station; I might say that these substation units act as .circuit controlling devices which permit a cycle ofimpulses to pass through the proper totalizing register forevery cycle that passes through the corresponding wage registers. The operation of the substation units has already been explained in the description of Figs. 3, 4, 5 and 8, and w; saw there that the armature remains stationary when the accumulating windings are energized concurrently with the transfer windings-,'and that it is rotated back and'forth when the "two sets of windings are energized intercurrently. Tn connection with Fig. 2, we

will take up a consideration of the circuits in which the transfer windings are included. The broken-away portion of the shaft shown at the left of Fig. 2 issupposed to bethe upnumber of substations. For the sake of simplicity but two substations have been'shown in the drawings. The reason for this gear ratio will presently appear. On the shaft TI are fixed three sets of transfer impulsedisks consisting oftthree disks each. The

first set of disks, indicated'by t0, zfib and 25a, is to connect the units ofsubstation S1 with the source of impulsibs, while the second set of disks 250, tb, taj is adapted to connect substation S2 withthe source of current. The third set of disks t0, 25"5, and ta is ,toafford a return path to the battery for the various impulses. The (1-, band 0-phases of the transfer windings of the units in substation Sl' are connected, respectively, to the conductors 1000, 100?) and 1000. It will be observed that in the caseof the transfer windings, the a-phase winding occupies the,

same position as the b-phase of the accumulating windings. The .b-phase of the transfer windings occupies the same'position as the a-phase of the accumulating windings, e,

while the c-phase of the transfer windings occupies the same position as the cephase of the accumulating windings. This is in ac ,cordance with what has been explained in connection with Figs. 3, {l and 5, where it will be observed that the accumulating windings occupy the positions in the order 'of a, b and 0, while the transfer windings are arranged in the order of 0, a and 0. The conductors 100a, 1001) and 1000 are connected withjthe brushes of the transfer impulsedisks ta, H) and t0 respectively. The different phases of the transfer windings of the units in substation S2 are connected to the conductors 200a, 2000 and 2000 in a manner similar to the connection of the units in substation S1, to the corresponding bus-conductors 100a, 1007) and 1000. .Busconductors 200a, 2006 and 2000 are connected, respectively, with the brushes of the impulse disks ta, tb and tc. The corresponding units of the various substations are connected in multiple tothe proper grand total registers. Thus the unitsTW and TW are connected to the conductor wwhich leads through the switch 90 to the grand total wage-register GTW. Similarly, the transfer windings of the Waste wage units W W and WW are connected in multiple to the the three-phase impulses.

conductor 'w'w which leads through the switch 90 to the total waste wage-register TWVV. By following out the connections of the other corresponding units of the substations, namely those indicated by SUl,

SU2, SU3 and SU'of substation S1 and units SU'l, SU'Q, SU3 and SU'l: of substation S2, it will befound that they are connected respectively with the job-totalregisters JTl, J T2, JT3 and JT4. I do not deem it neoessaryto trace every one of these circuits for the reason that they are similar to the circuits just traced for the units TW, TW, etc., and are furthermore apparent from a mere inspection of Fig. 2. All of the totalizing registers J T1 to J T4 are connected in multiple to the bus-conductors 300a, 3006 and 3000.

Let'us now trace one of the transfer circuits in the operation of that portion of my system shown in Fig. 2. For the sake of simplicity we will take substation unit SUl. As the shaft TI is rotated in the direction indicated by the arrow, the segment of disk ta will be the first one to engage its associ-v ated brush. At the same ti1ne,-however, the brush of disk ta will come into contact with one of the segments of that disk. The

switches 90 and '91 being in the position indicated, the battery circuit will be completed through the substation unit as follows: from one side of the battery B (which we may call the positive side) an impulse will flow through conductor 92, to the disk ta, thence through conductor 100a, through the a-phas transfer winding of the substation unit Ul, from there by way of conductor 93 to conductor jl, across the switch 90, through the. a-phase Winding of jobtotal register 'JTl, conductor 101a, common conductor 300a, switch 91, disk ta,, insulated section ti'of the shaft TI and by way pass through the substation unit SUl and. the job-total register JTl during one half a revolution of the shaft TI. During the second half of the revolution of that shaft, a cycle of impulses will be sent by Way of the disks t'a, t'b and tc through the units of substation S2. The disks ta, 6?) and 2fc will cooperate also with the disks ta, etc., to close the circuit in proper order for The disks t"a, etc., are capable of cooperating with both the-disks ta, etc, and the disks ta, etc., by

being each provided with two diametrically opposite segments. It will be observed that the angular position of the segment on disk ta is diametrically opposite to that of the segment on the corresponding disk t a. This diametric position also obtains with the seg ments of the'disks 6?), 6'1), to and tc. Moreover, the various angular positions occupied by the total segments on the disks t"a, tb and t c are respectively identical with the angular positions occupied by the pairs of disks z.ata, tbtb and tc-tc.

From the circuit connections above d scribed, it will be apparent that the units of any one substation are concurrently picked up fortransfer, while the substations themselves are selected successively for connection. The arrangement and number of transfer impulse disks on the shaft TI is such that all of the substations are picked up during every revolution of the shaft. The gear ratio of the connection between the impulse shaft IS and the transfer impulse shaft TI is such that during every fer impulses will be sent through the units of a substation. As I have shown and described my system as arbitrarily comprising two substations, the gear connection between the shafts IS and TI is such that the latter makes one revolution while the other makes two revolutions. For'three substations the gear ratio between the shafts ISv and TI would be '1 to 3, respectively, and so on for any number of substations.

Having already advanced a detailed descriptionof the operation of the substation units in connection with Fig. 8, I do not at this point deem it necessary to repeat such description in connection with the circuit arrangement shown in Fig. 2, 'since it will now be understood how thel'actuation of the workmens individual registers are duplicated in the proper classified-total registers at the final station. However, I have yet to call attention to the differential register represented by DR and diagrammatically indicated in Fig. 2 as having two sets of windings, one set being included in the connections leading from the grand total wage-register GTW and the other set reversely included in the connections leading from the total wage-register TWW. The

first set of windings is arranged in the order of a, .7) and 0, while the second set of windings is arranged in the order of b, a, and c. This is precisely similar to the arrangement of the two sets of windings on, the actuating mechanism shown in Figs. 3, 4 and 5. The armature of the difi'erential register DR is adapted to actuate numeral wheels. I have not considered it essential to an understanding of my invention to illustrate this mechanical detail, since it is something which, can be readily worked out by any revolution of the shaft IS, a cycle of transwindings b, a and c actuate the same backwardly, the amount of forward actuation will, of course, be the same as the amount of actuation of the register GTW while the.

amount of backward actuation will be the same as the amount of actuation of the register TWW. The resultant actuation of the numeral wheels of the differential register DR will be such as to indicate the difierence between the actuations of the registers GTW and TWW. The grand-total registers, as

well as the difierential register may be set back to zero by throwing the switch 91 into engagement withrthe contacts 95, 96and 97, and by moving the switches 90 into engagement with the contacts 98. This will close the circuit through the registers from. the one side of the battery B, to conductor 99, contacts 98, and from there across the switches 90 through the windings of theregisters to bus-conductors 300a, 3006, 3000, to contacts 95, 96, 97, across the switch 91, thence by means'of the disks t "a, t"b, t'"c to the other side of the battery. The actuation of the registers will, however, be-in the reverse direction for the reason that when the switch is thrown into engagement with the contacts 95, 96 and 97, the order in which the impulses are impressed upon the register windings is reversed. Whereas, during the accumulation oi these registers the phases were impressed 'n the order of a, b, 0 when the switch 91 engages the contacts 95, 96 and 97, the impulses are impressed in the order of b, a, c. T is is brought about bycon necting the co tact 97 with conductor 3000, connecting contact 96 with the conductor 390?), and connecting contact 95 with the conductor 300a; As each register is brought back to the zero position the circuit through the register is automatically interrupt'ed bythe opening of a pair of associated contacts, as was explained in. connection with Figs. 6 and 7. It is, of course, unnecessary that there should be' a separate battery for the transfer circuits. Conductors 92, 94 and 99 might as well be connected with the' battery B. For the sake of clearness, however, a separate battery has been shown in Fig; 2.

Inthe foregoing description of the preferred embodiment of my invention I have not endeavored to enumerate all of the many' advantages residing in the different features and arrangements, nor have I tried to set forth the many uses to which such features and arrangements might be put other than the specific use herein described for the purpose of conveying a clear understanding of my invention.
